EV Battery overview
Batteries are the key differentiator between the various EV manufacturers. The amount of energy stored in the battery determines the range of the EV, thought to be a major limitation on EV sales.


Consumers tend to worry that an EV with a range of 80 to 250 miles on a single charge would be inconvenient for long trips due to the time it takes to recharge the battery. Commercial batteries need to ensure there is quick recharge and less time between charges


The lithium-ion battery is important because it makes EVs expensive than ICEs. Battery costs per kilowatt-hour (kWh) declined from roughly $1,000 per kWh in 2010 to $227 in 2016


Lithium-ion batteries made up 70 percent of the rechargeable battery market in 2016
BNEF projects that global production capacity for lithium-ion batteries will increase from 103 gigawatt-hours (GWh) in the first quarter of 2017 to 273 GWh by 2021.


The battery manufacturing supply chain has three main parts:

cell manufacturing,

module manufacturing, and

pack assembly.
